The jury has retired in the case of a 17-year-old accused of shooting dead two British tourists in Florida last year.
Shawn Tyson is charged with two counts of first-degree murder after allegedly trying to rob, then gunning down, James Kouzaris, 24, and James Cooper, 25, in Sarasota.
The friends drunkenly walked into a public housing estate known as The Courts after a night out in central Sarasota in the early hours of 16 April.
Tyson was charged as an adult with two counts of first-degree murder and, if convicted, faces life in jail without parole.
The teenager, who was 16 at the time of the alleged murders, has not given evidence in the case, which opened last Thursday, and the defence called just one witness.
After instructions from Judge Rick De Furia, the jury at Sarasota County Courthouse was sent out to start its deliberations.
